Description

Technical Field

[0001] The present invention relates to the technical field of bridge pile hole slag fishing devices, and specifically relates to a device for treating sediment in bridge pile holes. Background Art

[0002] When the bored cast-in-place pile construction technology is adopted in building pile foundation projects, if slurry wall protection is adopted, after the hole is formed and the steel reinforcement cage is lowered and installed, due to the long time required, during this period, under the action of the self-weight of the slurry in the hole, some of the particulate matter suspended in the slurry precipitates at the bottom of the hole. Before the pile foundation concrete is poured, it is necessary to clean the sediment at the bottom of the hole. There are currently two conventional methods. One is to rely on the impact force of the first batch of pile foundation concrete pouring to blow up the sediment at the bottom of the hole so that it remains suspended in the slurry. The other is to use a slag fishing device to remove the sediment at the bottom of the hole. For the first cleaning method, if there is a lot of sediment, there will still be some sediment that adheres together and stays at the bottom of the pile. This part of the sediment is wrapped by the concrete, and its strength is less than that of the surrounding solidified concrete, posing a safety hazard. For the second cleaning method, during the process of the slag fishing device rising, it is easy for the sediment to fall off, and multiple repeated operations are required, which is laborious and difficult to clean the sediment completely. Moreover, during the multiple repeated slag fishing processes, the slag fishing device is prone to hitting the inner wall of the pile hole, causing a negative impact on the inner wall of the pile hole. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a device for treating sediment in bridge pile holes. The jet pipe blows up the loose sediment in the pile hole, and the suction hard pipe transports the blown-up sediment into the suction box through the suction hose. According to the signal data returned by the radar antenna, it is ensured that the cleaning process has no negative impact on the inner wall of the pile hole, reducing the number of slag fishing times, reducing the labor intensity, reducing the frequency of hitting the inner wall of the pile hole, and ensuring that the cleaning process is safe and reliable and will not have a negative impact on the pile hole.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

The upper connecting rod is slidably connected to the lower connecting rod, and the hard bottom plate is rotatably connected to the lower connecting rod. The secondary cleaning mechanism includes a blower, an air supply pipe that can extend into the pile hole, a spray pipe, and a support seat for coiling the air supply pipe. One end of the air supply pipe is fixedly connected to the blower, and the other end of the air supply pipe is fixedly connected to the spray pipe. The spray pipe is provided with 1 main spray port and 2 symmetric side spray ports. The support seat is fixedly connected to the outer wall of the blower. The suction mechanism includes a suction box installed at the bottom end of the blower, a suction hose extending into the interior of the suction box, and a suction hard pipe connected to the bottom end of the suction hose. A suction motor is installed in the suction box, and a screening net is installed on the inner wall of the suction hard pipe. The geological inspection mechanism includes a radar antenna and a geological radar installed on the side wall of the suction box. The radar antenna is connected to the geological radar through a connecting cable.

[0006] Further, the primary cleaning mechanism is provided with a traction line and 2 symmetric soft side plates. One end of the soft side plate is fixedly connected to the hard bottom plate, and the other end of the soft side plate is fixedly connected to the lower connecting rod. One end of the traction line is connected to the hard bottom plate, and the other end of the traction line is connected to the upper connecting rod.

[0007] Further, the secondary cleaning mechanism is provided with a guiding rod. The guiding rod includes a lower rod body and an upper rod body. The lower rod body is fixedly connected to the spray pipe, and the upper rod body is rotatably connected to the lower rod body through a rotating shaft.

[0008] Further, the support seat is provided with a central positioning column, a limiting arm, and an intercepting plate. The limiting arm is sleeved on the central positioning column, and the intercepting plate is sleeved on the limiting arm. The outer cover of the blower is provided with a plugging hole that matches the intercepting plate.

[0009] Further, the suction hard pipe includes a straight pipe and an inclined pipe. The straight pipe is threadedly connected to the suction hose, and a screening net is installed on the inner wall of the straight pipe. The included angle between the inclined pipe and the straight pipe ranges from 110° to 120°.

[0010] Further, a placing cylinder is installed on the side wall of the suction box opposite to the geological radar. The primary cleaning mechanism is inserted into the placing cylinder, and the placing cylinder is provided with an opening groove that matches the hard bottom plate.

[0011] Further, the geological inspection mechanism is provided with an upper wire winding column and a lower wire winding column. Both the upper wire winding column and the lower wire winding column are fixedly connected to the outer cover of the blower.

[0012] Further, the geological inspection mechanism is provided with limiting blocks, and the limiting blocks are respectively rotatably connected to the upper wire winding column and the lower wire winding column through rotating shafts.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0014] 1) The present invention uses a hard bottom plate to dig out larger sediment in the pile hole, and initially loosens the sediment bonded together during the movement of the hard bottom plate. Then, the jet pipe is sent into the pile hole through the air supply pipe, the suction hard pipe is aligned with the pile hole, the blower is started, the jet pipe blows up the loose sediment in the pile hole, and the suction hard pipe transports the blown-up sediment into the suction box through the suction hose. After the cleaning is completed, the radar antenna is placed at the bottom of the pile hole through the connecting cable. According to the signal data returned by the radar antenna, it is ensured that the cleaning process has no negative impact on the inner wall of the pile hole, reducing the number of slag fishing times, reducing the labor intensity, reducing the frequency of impact with the inner wall of the pile hole, and ensuring that the cleaning process is safe and reliable without having a negative impact on the pile hole;

[0015] 2) Pull the traction line, and the traction line can drive the hard bottom plate to rotate upward around the lower connecting rod. The soft side plate can bend synchronously with the rotation of the hard bottom plate. The angle between the hard bottom plate and the lower connecting rod changes from a right angle to an acute angle. During the process of the upper connecting rod and the lower connecting rod moving upward and leaving the pile hole, it is prevented that the large-sized sediment wrapped by the hard bottom plate and the soft side plate falls back into the pile hole;

[0016] 3) Rotate the upper rod body until the upper rod body and the lower rod body are on the same straight line, and move down the guiding rod. While sending the jet pipe into the pile hole, control the orientations of the main jet orifice and the two symmetric side jet orifices, so that the main jet orifice is aligned with the bottom end of the pile hole to ensure the efficiency of stirring the sediment;

[0017] 4) The primary cleaning mechanism is stored through the placement cylinder, the air supply pipe is stably wound through the support seat, and the connecting cable is stably wound through the upper wire winding column and the lower wire winding column, so that each component maintains a clear and independent state, preventing confusion in use.
